Notes

Progress bar is written to STDOUT, and disabled when command is piped. Progress advances with $progress->tick(), and completes with $progress->finish(). Process bar also indicates elapsed time and expected total time.

# `wp user generate` ticks progress bar each time a new user is created.
#
# $ wp user generate --count=500
# Generating users  22 % [=======>                             ] 0:05 / 0:23

$progress = \WP_CLI\Utils\make_progress_bar( 'Generating users', $count );
for ( $i = 0; $i < $count; $i++ ) {
    // uses wp_insert_user() to insert the user
    $progress->tick();
}
$progress->finish();
